Question

There are many operations in oil and gas industry such as drilling, casing, cementing, perforation, well logging and well stimulation. Mention the possible hazard (2.5 marks) and safety measures (2.5 marks) that an engineer must keep in mind during cementing operation.

Answer 1

The possible hazards during cementing operation are:-

(1) Get strucked by high pressure line failures

(2) Falling byhigh pressure connection failures results due to worn hammer

(3) Irritation of eyes,nose ,throat ,respiratory system etc due to exposure of cement dust.

(4) Lung cancer and silicosis due to exposure of silica during cementing operation.

(5) Severe skin damage and irritation of skin from chemical burns.

(6)Injury of workers due to use of unguarded machinery and old equipments .

(7) Hearing loss of workers due to excessive exposure to sounds and vibration from cementing mecheniary.

(8) Due to improper lifting of materials it can cause strains in body and lead to sprains.

(9) Cementing on confined spaces may lead to breathing problems to workers .

(10)Falling due to slippery surface caused during cementing operation

The safety measures that an engineer must keep in mind during cementing operation are :-

(1) Proper alignment of high pressure lines during operation .

(2) By proper inspection of equipment at regular intervels during cementing operation .

(3) Preplan the location of equipments before cementing operation.

(4)Use proper lifting techniques, mechanical lifting aids whenever neccesary.

(5)Wear properly personal protective equipment for respiratory and fall protection.

(6) Conduct pre job inspection to avoid any kind of hazards during cementing operation .

(7) Clear all non essential personnel before operation .

(8) For direct equipment movement use spotter so that work can be performed properly.

(9) By keeping working area properly levelled in order to avoid slipping .

(8) By giving proper instructions to workers in order to avoid hazard during operation.
